V'APQRIZING AND IGNITING MEANS FOR HYYDEQCAEEKQN-LAMPS.

Specification of letters Eatent.

Application filed November 6, 1908. Serial No, 6-6134? which the following is a specification.

This invention relates to a means for initially vaporizing and for igniting a hydrocarbon lamp of that class exemplified in the Grillett lamp, and my improvement is directed to the provision of asimple and convenient insane for the. initial vaporization and ignition 0f the gas where the lamps are used in positions Where lgnition is. inconvenient by the means at. present used. I accomplish this by roviding the vaporizing tube with a coil of wire through which an electric current may be passed that will heat the wire to redness or to such a degree that will vaporize the hydro-carbon, and in series with this coil immediately over the globe of the burner l furnish a short section of platinum or other Wire which with the same current will. be heated to incandescence or to a temperature that will ignite the mixed air and gas as it is delivered from the burner of the lamp. With this arrangement, a current being turned through the vaporizing coil and the igniting wire, and the fluid hydrocarbon admitted under pressure to, the vaporizing tube, that hydro-carbon will be vaporized by the heat from the coil and passing through the Bunsen mixer will be delivered from the burner; and coming in contact with the incandescent latinum wire will be ignited thereby. Aiter which the electric current may be cut oil and the vaporization allowed to proceed in the usual'nianner by the waste heat from the lamp.

The invention is particularly described in the following specification, and illustrated. in the drawings by which it is accompanied, in which:

Figure 1 is a. side elevation and part secticn of a lamp showing the application of my initial vaporizing and igniting device thereto, and Fig. 2, an enlarged detail of the vaporizing tube showing the application of the initial vaporizing and igniting coils thereto.

In these drawings 2 and 3 represent the hollow suspension frame or" the lamp, through one of which, 2, the fluid hydrocarbon is delivered under pressure to the 'are of twisted wire bentaround band.

vaporizingtube a in the usual neer. The Bunsen air mr-rer is placed in downtake 6 through which the mixed air and gas is delivered to the burner 7, in order to atford a greater area for vaporization, but this arrangement does not constitutea necessary part of the invention. The incan descent mantle, which is not shown in the drawing; is inclosed by the globe 8 which is carried up closer tov the vaporizing tuhethan is thensual practice, as with my vaporizing and igniting device there is no need to pro vide accommodation for the application of the alcohol torch which lSbOmlBOlllY used to secure the initial vaporization and ignition. To the vaporizing tube a is applied a coil 10 to which is conveyed a current from an external electric circuit 9, the wires, suitably insulated, passing to the vaporizing tube down one of the suspension tubes 3 of the lamp. "the wire of this coil. 16* is of such material and so proportioned to the strength of the current used, that it will be heated to redness, or to a temperature suiiicient to vaporize the hydro-carbon. The coil is be applied in any suitable manner, but is preferably coiled on the outside of the tube, a thin sheet 11 of mica being first applied to the tube to electrically insulate the wire of the coil from the metal of the tube. The coil is then inclosed with an outer layer 1-2 of mica and an outer shea ring of thin sheet metal. is spirally wrapped to hold the mica in place and protect it from injury. These mica layers though necessarily exaggerated. in thickness in Fig. 2. of the drawing, need only be very-thin so that they will not interfere to any material extent with the passage of the heat from the coil inward. to the tube during initial vaporization or with the. passage of the heat the lamp to her-- really vaporize the hydro-r.

A hydro-carbon lamp, having a mixing tube, a vaporizing tube and a burner connected therewith, together with means for supplying a hydro-carbon through the V211)- orizing tube to the burner, an electric heat -1ng unit on the vaporizing tube for-vaporizing the hydro-carbon within the tube, an electrical igniting unit supported on the vaporizing tube to ignite the vaporized hydro-carbon and air from the burner, and

means for supporting said vaporizing tube.

oyer said burner to be heated by the ignited hydro-carbon vapor.
